This is the 3rd post in the series. Previous post see here.

Rich Text Format (RTF)

The Rich Text Format (RTF) is one of the document formats supported by Microsoft Word and many other word processing applications. RTF is a human readable word processing format intended for interchange between different applications on various platforms and it has been around for 20 years. The new XML-based formats are becoming more common, but RTF is still being supported and updated by Microsoft. The latest version is RTF 1.9 Specification from January 2007.

RTF features in Aspose.Words:

·          Aspose.Words can read and write files in the RTF format of any version.

·          Aspose.Words supports over 95% of the RTF 1.8 Specification, which makes Aspose.Words an excellent and lossless tool for working with RTF documents.

·          Unknown keywords (unsupported or from newer specifications) are safely ignored.

The RTF specification is a set of keywords. There are over 1400 keywords in the RTF 1.8 Specification. Aspose.Words fully supports (reads and writes) over 1300 of those keywords (over 95%). It is hard to find a similar level of implementation in other products.
